화학적 성질
yellow to light brown crystalline powder용도
4-Chloro-7-nitrobenzofurazan is nonfluorescent until it reacts with primary or secondary amines to produce a fluorescent product. 4-Chloro-7-nitrobenzofurazan has been extensively used as a derivatizing reagent for chromatography analysis of amino acids and low molecular weight amines.정의
ChEBI: A benzoxadiazole that is 2,1,3-benzoxadiazole which is substituted at position 4 by chlorine and at position 7 by a nitro group.일반 설명
4-Chloro-7-nitrobenzofurazan (NBD-Cl) is a highly sensitive chromogenic and fluorogenic reagent. It is reported to react spontaneously with trans-1-methoxy-3-(trimethylsilyloxy)-1,3-butadiene (Danishefsky′s diene), to afford regioselectively the silyl enol ether, via normal electron-demand Diels-Alder (NEDDA) reaction. A study of the molecular structure, vibrational spectra and NBO (Natural Bond Orbital) analysis of NBD–Cl has been undertaken. Its utility as a pre-column derivatization agent has been examined.Purification Methods
Wash the solid with H2O, and it recrystallises from aqueous EtOH (1:1) as pale yellow needles. It sublimes in a vacuum [Gosh & Whitehouse Biochem J 108 155 1968, UV, NMR: Bolton et al. J Chem Soc 1004 1966].4-Chloro-7-nitrobenzofurazan 준비 용품 및 원자재
